In one move, you can jump from the position i i to the position i - a_i i−ai (if 1 \le i - a_i 1 ≤ i− ai ) or to the position i + a_i i+ ai (if i + a_i \le n i+ai ≤ n ). WebApr 7, 2024 · 利用Dijkstra (在这里可行的单源最短路算法)可以很容易算出从节点x到任意点的最短距离,现在需要求解从任意点到节点x的最短距离. 利用反向建图: 额外建立一个有向图,该图中所有的边都与原图方向相反,权值不变. 在这张图中再次使用Dijkstra求出从节点x到任意点的最短距离. 在这张图上得到的最短距离dist [i]就是 在原图上从节点i到节点x的最短距离. …
